Hi there, I did that last year and I had the same symptoms develop. Its def your body going through withdrawals and its in shock. You have to be very careful when eliminating things like "sugar" from your diet because sugar is more addicting than any drug, even heroin. I've taken several classes in school in diet/nutrition and learned a lot about this stuff. It's best to only eliminate one thing at a time. And sugar is the hardest food to do, so it takes a long time (or should) to wean yourself. Most people just go cold turkey and typically it takes 2-3 weeks for symptoms to start, and most people can't handle them and they give up or go back.
Also, be careful, sometimes when some people eliminate sugar (something they have fed their bodies their entire lives, their make up (chemicals) hormones, and blood sugar, and other metabolic chemicals can get all whacky and literally cause a chain of unfortunate things to happen. It's def something that should be highly researched and done slowly, to accomplish without too many harsh side effects.
